Is the Android version of Podtrapper registering to the Media Button functionality?
When playing podcast, media button still starts/stops the stock android music player.
(The 'Media Button' is sometimes part of handset hardware, others generally on the headphone cord).
This page gives code for registering the app to respond to the button...
